Me describe at least two hazardous conditions that exist in space and the technological features a spacecraft must have in order to protect the astronauts from these hazards.

Space travellers or astronauts may have to face hazardous health conditions like hypothermia due to the absence of heat. Meteor showers can also cause a serious threat to the spacecraft and the astronauts in it.

Explanation:

When space travellers or astronauts are on a long space mission, they are vulnerable to a number of health hazards. Hypothermia (death due to freezing) and meteor showers are the ones that can cause the greatest damage to life and property in the space. To protect the astronauts from hypothermia, the spacecraft needs to be equipped with proper insulation so that the spacecraft doesn't stand vulnerable to temperature drops. To protect the astronauts from meteor showers, the spacecraft should be equipped with the most advanced sensors and engines with a powerful thrust capable enough to allow the spacecraft to change its path quickly.

is Earth round Yes, the Earth is roughly a sphereWhat is the shape of EarthFigure of the Earth is a term of art in geodesy that refers to the size and shape used to model Earth. The size and shape it refers to depend on context, including the precision needed for the model. The sphere is an approximation of the figure of the Earth that is satisfactory for many purposes.
